Specification formingpart of Letters Patent No. sl?. (laten Jennery 16,1866.

To all whom it may concern:

Beit known thetLE. E. HOPKINS, of Phila.- delphin, `Pennsylvanie, haveinvented'ztn Improved 'Writer-Cooler; and I do hereby declare thefollowing,r to be a full, clear, and exact description of thesuine,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

My invention consists ot" a water-cooler cornposed ot' an inner end anouter casing, e reservoir, and upipe, arranged, as describedhereinafter, so that the inner .casing can be filled with Water withoutadmitting air to the same.

1n order to enable others skilled in the art to ineke and use myinvention, will now proceed to describe its construction and opera-LlUll.

0n reference to the accompanying drawings, which forni e part of thisspecification, Figure l isn sectional elevation oi' my improvedwater-cooler, and Fig. 2 n plein view with the top removed.

A is n cylindrical cese,to the top of which is fitted .i lidha, and atone side of which, near the top, is n smell reservoir, B. Vithin they,case A is it square vessel, G, which is provided with e top, D, andwith suitable legs e e, and

from the side ot' this vessel, near the bottom of the saine, projects :itube, f, which extends through the outer casing, A. A short tube,,projects into the cese A from the bottom of the reservoir B, and fromthe side of the vessel '(1, zt short distance below'the tube i, projectse smaller tube,fi,and to each tube is connected one end ot' a tube, K,of rubber or other `suitable material.

lt is well known that with water-coolers as usually constructed there isn, great Weste of ice on account ot' the shape ot' the interior of thecooler, the latter being round and necessitatin g;4 the cutting away ofthe corners of theV ice, or of breaking the letter in to small pieces.

ln the ordinary coolers, nlso,the meltingof the ice is hastened bythe`frequent removal ot' the cover of the cooler and admitting Warm sir tothe interior when the cooler has to be replenished with Water.- l

By melting the interior of myvcooler of such shape and size that e'blockot' ice may be deposited in the saine withoutcutting uwityeny portionot' it, the waste from the letter cause is prevented, while et the seinetime it is not necessary to' use e cooler of snylsrger external sizethen those of theord'inery form usu- 'ally employed for the same amountof ice.

When the ice and Water lherve been 'placed in the cooler both the vesselD and the cnsingA are covered with their respective lids, and the coolWater, when required, is drawn from the. cooler through the pipe f.

When the supply, of weiter has to be replenished it is introduced intothe reservoir B,- trom which it hows through the pipe K into the vesselC. 4

It will be seen that the pipe k is of such a.

form that e portion'of the water rnnust remain- Yin the lower bentportion ot' the'same, es inordinery traps, this water efectuelly closingthe pipe end forming e. trap, by which all commu nicetion between theexternal air and that in the vessel D is closed, and the waste of iceand heating of the water which would ensue from the removal of the lidsare eectually pre- Vented.

The space between the two cesings may, it' desirable, be lled with anysuitable non-conducting material.

I claim as my invention and desire to secure by Letters Patent- `Awater-cooler composed of an outer casing, A, ain inner casing, c, nreservoinB, and a, pipe, K, the latter being combined with the casingand forming en inverted siphon,es and for the purpose described.

p In testimony whereof I have signed my neme to this specification inthe presence of two subscribing Witnesses.
